6(x-4)-2= 6x-24-2 = 6x-26
2(x+1)-3(x-1)= 2x+2-3x+3=-x+5
-3(y-2)+4(y+2)=-3y+6+4y+8=y+14
5(x-y-1)-4(x+2)=5x-5y-5-4x-8=x-5y-13
2(3a+b)-2(a-b)=6a+2b-2a+2b=4a+4b
½(4x-4)-2x=2x-2-2x=-2
x(x-1)-3(x²-x)=x²-x-3x²+3x=-2x²+2x
5a(a-3)-3a(a-5)=5a²-15a-3a²+15a=2a²
Pomogłem ?
To licze na naj :D
6(x-4)-2=6x-24-2=6x-26
2(x+1)-3(x-1)=2x+3x+1=5x+1
-3(y-2)+4(y+2)=-3y+6+4y+8=y+14
5(x-y-1)-4(x+2)=5x-5y-5-4x-8=x-5y-13
2(3a+b)-2(a-b)=6a+2b-2a+2b=4a+4b
jedna druga (4x-4)-2x=2x-2-2x=-2
x(x-1)-3(x do kwadratu -x)=x^2-x-3x^{2}+3x=4x^{2}+2x
5a(a-3)-3a(a-5)=5a^{2}-15a-3a^{2}+15a=2a^{2}
